Here is a little strategy of how to make some gold from using exploration.
1. You should be a warlock. You should have 2 other people who know how to do the exploit.
2. Go to a major city where you know an exploit is. (Under stormwind, on top of ironforge auction house etc.)
3. Get to this place and have lots of soul shards ready.
4. In trade chat tell people you will summon them to this place for 3g or so. For instance,"summons inside gryphon tunnel in ironforge for 3g!"
It's a pretty easy way to make a little cash if you're REALLY lazy.
